Laboratory of Space Geophysical and Oceanographic Studies (LEGOS joint research unit)

The LEGOS research and teaching scientific fields include oceanography and the water cycle in the broadest sense, with the physics of the oceanic, hydrological, cryospheric and atmospheric components, including coastal and climatic components, as well as marine biogeochemistry and geochemistry.
In addition, several Observation Services and working groups allow the lab know-how to be shared, capitalised and disseminated.
